US Patent:

40620050, Dec 6, 1977

Filed:

Nov 4, 1975

Appl. No.:

5/628471

Inventors:

Gerald Lewis Freed - Highland Park NJ
David S. Lerner - Fanwood NJ

Assignee:

Lockheed Electronics Co., Inc. - Plainfield NJ

International Classification:

G08C 1938

US Classification:

340198

Abstract:

Circuitry monitors a plurality of rotating shafts, and provides a corresponding plurality of binary output words each characterizing the angular position of an associated shaft. Synchro and Scott "T" per-shaft monitoring elements are sampled by common multiplexer-central processor units which provide derived shaft position and shaft rate information to an appropriate one of plural shaft position output processors. In accordance with varying aspects of the present invention, the output processors include a rate multiplier controlled by the computer generated shaft rate signal, and a counter presetable by the CPU generated position signal, and advanced (decremented) by the rate multiplier output.

Appl. No.:

6/681936

Inventors:

David R. Lerner - Mount Vernon NY

International Classification:

H02B 110

US Classification:

361377

Abstract:

An ultrahighlight fluorescent light mounting system for filming, particularly in color. A head carries the fluorescent tubes and a removable light shield while the ballast is positioned in a container remote from the head. The head is set upon and swivable about an upper post, which is rotatably connected to a lower post, which in turn is set upon and swivable about a swivel piece extending from a standard stand. The head, light shield, first post, second post, stand, and ballast can all be dissembled from one another and placed in carrying cases.

International Classification:

G06F 1542

US Classification:

36441301

Abstract:

A device for monitoring medication of a patient and for prompting the patient into certain medication taking schedule and/or certain programming steps and routines. The device has a plurality of compartments, each of which may store medication and an electrical signaling system to emit medication alert signals from time-to-time, each of which the signals indicates (a) that medication should be taken, (b) from which compartment the medication should be taken, (c) and the quantity of medication to be taken. If a designated compartment is not opened and closed within a predetermined period of time, the electrical signaling system will sound an alarm. If each designated compartment is opened and closed, the take-medication signal and the alarm (if operating) are turned off and the event is recorded for later review. The device includes a display having a substantially continuous display area having portions thereof closely adjacent to each compartment.

Appl. No.:

8/406713

Inventors:

David A. Lerner - Metuchen NJ

Assignee:

LifeSigns Corporation - Minneapolis MN

International Classification:

A61B 800

US Classification:

12866201

Abstract:

An ultrasonic blood flow velocimeter for measuring the velocity of blood flowing in an artery or vein beneath the skin of a patient, by insonating the tissue with ultrasonic energy, receiving doppler-shifted signals reflected by the blood and processing the signals to determine blood velocity. The signal processing and calculations result in an accurate measure of velocity which is independent of the angle between the probe and the blood flow. This gives more accurate results than other ultrasonic methods which approximate results because of angle dependency and the fact that in general this angle is unknown. The invention can also detect and discriminate between forward and reverse flows, even when they occur simultaneously, as in the case of insonating an artery and vein with opposite flows. The invention can also measure peak flow velocity, though efficient time domain processing of signals.

Appl. No.:

5/628464

Inventors:

David S. Lerner - Fanwood NJ

Assignee:

Lockheed Electronics Co., Inc. - Plainfield NJ

International Classification:

G01R 3102

US Classification:

324 51

Abstract:

A circuit for monitoring the accuracy of the phase shift produced in an r. f. power distribution network in which the phase shift network includes diodes, means for sensing the conductive state of the terminating diodes, and structure for comparing the state of the diodes against a desired condition to provide a warning indication in the event the diodes are not in the proper condition to provide the desired phase shift.

International Classification:

D05B 4500
D05B 5900

US Classification:

112278

Abstract:

A bobbin thread level detection and display arrangement for a sewing machine includes an array of light emitting diodes which are activated to convey to the sewing machine operator an indication of the quantity of thread left of the bobbin. To control the light emitting diodes, an arrangement utilizing a light source and a phototransistor is arranged proximate the bobbin. The circuitry for controlling the activation of the light emitting diodes also provides for a "fading in" of the individual light emitting diodes to provide a display in the nature of a bar graph.

Abstract:

A device for monitoring medication of a patient and for prompting the patient into certain medication taking schedule and/or certain programming steps and routines. The device has a plurality of compartments, each of which may store medication, and an electrical signaling system to emit medication alert signals from time-to-time, each of which said signals indicates (a) that medication should be taken, (b) from which compartment the medication should be taken, (c) and the quantity of medication to be taken. If a designated compartment is not opened and closed within a predetermined period of time, the electrical signaling system will display an alarm and the event will be recorded as a missed medication event, unless the patient then opens the designated compartment. If each designated compartment is opened and closed, the take-medication signal and the alarm (if operating) are turned off and the event is recorded for later review. The device may be constructed in one piece with hinged doors for each pill compartment, or each pill compartment may be a separate "drawer" sliding into a main unit.
